Power factor correction (PFC) is an important part of the power supply design, ensuring that the power drawn from a source is in the correct phase and has sufficient quality to support the application. The NCP1910B65DWR2G is a PMIC (Power Management IC) that offers PFC to control and monitor the power factor of switched mode power supplies (SMPS) with high efficiency, accuracy and signal integrity performance.

NCP1910B65DWR2G is optimized for applications such as TVs, white goods, industrial lighting, and other types of products with multiple output power sources. This PMIC integrates MOSFET, IGBT and FET drivers that are capable of driving large currents and voltages. It also provides a variety of protection functions and error correction mechanisms to help protect the power supply from various external influences.

The NCP1910B65DWR2G features a wide range of operating voltage, which makes it suitable for a variety of power requirements, such as AC and DC power systems. It can deliver up to 65W of continuous output power, making it ideal for high-power applications. It also features an integrated power factor correction and provides high efficiency levels, ensuring that the power drawn from the source is in the correct phase.

The NCP1910B65DWR2G features a three-phase buck converter, which is specifically designed for high-power buck converters. It offers high efficiency, thanks to its low gate resistance and low gate charge. The three-phase architecture increases efficiency by reducing both the input current and input capacitor size. The NCP1910B65DWR2G also provides a cycle-by-cycle current limitation, which helps prevent high currents from causing damage to the power supply.

The NCP1910B65DWR2G also features an integrated PFC that provides improved power factor correction. With the PFC, the power supply does not draw current or voltage from the source continuously, but rather the current drawn follows a sinusoidal waveform, with low current ripple. This reduces losses in the power transfer, improving overall power efficiency. The PFC also ensures that power is more evenly distributed among the output power sources of the power supply.

The NCP1910B65DWR2G also includes over-temperature protection, as well as overvoltage and undervoltage protection. It also features a unique fault detection system, which detects any abnormality in the input power supply and immediately shuts down the system. This prevents any damage caused by an over voltage or under voltage issue.

Overall, the NCP1910B65DWR2G is an ideal PMIC for power factor correction applications. It offers high efficiency and accuracy, as well as a variety of protection functions to ensure system reliability. Its three-phase buck converter architecture offer flexibility and higher efficiency, and its integrated PFC provides improved power factor correction. The NCP1910B65DWR2G is also an ideal solution for applications such as TVs, white goods, industrial lighting, and other types of products with multiple output power sources.
